Abstract:

Objective

To observe the safety and efficacy of endoscopic submucosal dissection(ESD)in the treatment of non-ampullary duodenal laterally spreading tumors(LSTs).

Methods

The clinical data of 62 cases of non-ampullary duodenal LSTs from January 2017 to June 2020 were selected,and the patients were randomly divided into two groups:the ESD group and EMR group,with 31 cases in each group. The EMR group underwent endoscopic mucosal resection,and the ESD group underwent endoscopic submucosal dissection. Data processing software SPSS 22.0. Perioperative relevant indexes,inflammatory indexes and other measurement data were expressed by(

±s),and independent t test was performed. Postoperative complications were counted by χ2 test. Kaplan-Meier parallel log-rank test was used for survival analysis(P<0.05)was statistically significant.

Results

The operation time of ESD group was significantly longer than that of EMR group,while the intraoperative blood loss,total resection rate,R0 resection rate and postoperative hospital stay of ESD group were significantly better than those of EMR group(P<0.05),and there was no significant difference in postoperative complications between the two groups(P>0.05). The levels of CRP,IL-6 and TNF-α in both groups were significantly increased 24 h after surgery,and the three levels in ESD group were significantly lower than those in EMR group,the differences were statistically significant(P<0.05).The median follow-up period was 23 months,the cumulative disease-free survival rate was 80.6% in the EMR group and 100% in the ESD group,he difference between the two groups was statistically significant(P<0.05).

Conclusion

ESD treatment of non-ampullary duodenal LSTs is safe and effective,Which can not only effectively control the risk of surgery,but also has better effect of resection,and improve the prognosis of patients.
